DATA INTERPRETATION 


and comparing alternative interpretation scenarios with relevant geophysical and geological data, more accurate interpretations and lower prospect risk are possible. Te result is better decisions, higher success ratios, lower finding costs and fewer dry holes. Its 3D tools also allow users to develop


a rich, searchable history that is invaluable for calculating reserves, identifying and correcting mistakes, auditing and relating data types together. Users have the choice of automatically capturing the interpretation history or inserting comments on the interpreted data set. Search tools help locate the right types of data using key words. Tis capability supports the 4D workflow and boosts the superiority of data management.


Poststack seismic processing Te software provides a highly integrated interpretation environment. Multi-discipline data types and cross discipline workflows are immediately accessible to enhance or confirm analysis and interpretations. SeisWorks is highly integrated with Landmark’s suite of geotechnical applications for poststack seismic processing, attribute analysis tools, and geological applications. Multiple horizon tracking methods are provided. Automated methods offer rapid horizon picking in any


direction across a survey. In difficult areas manual picking provides the ultimate control. Interpretation from well data is easily


incorporated into the seismic interpretation process. SeisWorks reads real-time updates from PetroWorks and StratWorks through OpenWorks. Information from SeisWorks can be sent to StratWorks and PetroWorks via a Pointing Dispatcher (PD) interactive utility. Depth-to-time utilities, integrated display of the well track, geologic tops and curves along the horizontal or recumbent well bore, synthetic overlays, and basic synthetic manipulation combine to leverage geologic data in a seismic interpretation workflow. PowerView functionality provides a novel


and innovative visual analysis environment for viewing maps or cross-sections. Simultaneous displays of virtually unlimited number of map and/or cross-section windows are supported. Cursor movements, cross hairs, zoom control, and polygon selection are shared (mimicked) between all the windows, yet each window can have independent colour ramps to highlight the specific data or attribute in each window. PowerView map and cross-section views


support multiple data layers and RGB transparency control for attribute ‘blending’, a powerful analysis technique for high


resolution spectral decomposition imaging. On-the-fly mathematical operations provide a novel way to look at differences in data. “A perfect analysis tool for a 4-D seismic interpretation,” says the company. Power Calculator creates logical and


mathematical equations for operations on horizons. Algorithms and workflows can be saved in a flowchart format then repeated from day to day or from dataset to dataset. Te drag-and-drop feature streamlines data input into any flowchart. Output can be previewed before writing out the results to disk. For its part, Petrel seismic interpretation


software from Schlumberger seamlessly combines the workflows of 2D interpretation with the visual and performance benefits of 3D volume interpretation. Users can leverage an interpretation


environment unified with geology, reservoir modelling, and reservoir engineering domains and have the ability to rapidly interpret seismic data and compare the results with other data in a project. Effortlessly move from interpretation to structural model building to property modelling and back, eliminating the gaps and inevitable knowledge and data loss of traditional systems that require handoffs from one technical domain to the next.
